Moisture Correction for Coal Analysis

Moisture in coal varies from the point where it is received to the point where it enters the boiler. The variation in the moisture affects the reported heating value and analysis. The laboratory analysis is required to be corrected to the actual moisture content in the field. Methods for applying these corrections are explained here.

Moisture Content Impact on the Self-Heating Rate of a

Many studies have also been completed examining how differing levels of coal moisture content affect the self-heating rate of coals. These have produced conflicting results. Sondreal and Ellman (1974) found that for a lignite sample there was a critical moisture content at which the rate of oxidation reached a maximum. This finding is

Moisture in Coal, Coal Analysis, Kentucky Geological

Moisture absorbs heat, so high moisture content in coal reduces the relative efficiency of heating when a coal is combusted. This is why low-rank, high-moisture coals have lower calorific values (Btu/lb) than high-rank, low-moisture coals. Moisture adds weight to coal, and also contributes to spontaneous combustion in low-rank coals, and as
